List of legacy HTML named character references that don’t need a trailing semicolon.

Contents

What is this?

This is a list of certain named character references, that due to legacy reasons, don’t need a trailing semicolon in HTML. For example, &copy is perfectly fine for ©!

When should I use this?

Maybe when you’re writing an HTML parser or minifier, but otherwise probably never! Even then, it might be better to use parse-entities or stringify-entities.

Install

This package is ESM only. In Node.js (version 12.20+, 14.14+, or 16.0+), install with npm:

npm install character-entities-legacy

In Deno with esm.sh:

import {characterEntitiesLegacy} from 'https://esm.sh/character-entities-legacy@2'

In browsers with esm.sh:

<script type="module">
  import {characterEntitiesLegacy} from 'https://esm.sh/character-entities-legacy@2?bundle'
</script>

Use

import {characterEntitiesLegacy} from 'character-entities-legacy'

console.log(characterEntitiesLegacy.includes('copy')) // => true
console.log(characterEntitiesLegacy.includes('frac34')) // => true
console.log(characterEntitiesLegacy.includes('sup1')) // => true
